Chain slack measuring method for use in tracked vehicle, involves fixing three extension elements at upper trough of chain such that two extension elements are arranged at length section, and third extension element is arranged on center

摘要

The method involves fixing three extension elements (3.1,3.2,3.3) at the upper trough (2) of the chain such that two extension elements are arranged at the length section of the trough. The third extension element is arranged on the center (M) of the section. The ends of a flexible comparison element (4) are fixed on the extension elements, such that the comparison element is stretched in horizontal direction. The difference between the vertical distance of the comparison element ends and section center is determined by the third extension element carrying a meter scale (3.32).
